The Defibrillator (ICD)

Preventing sudden heart attacks

If you have a weak heart, you’re at a higher risk for sudden cardiac arrest. Sudden cardiac arrest is caused by an irregular heartbeat (arrhythmia) that prevents the heart from pumping blood to the brain and vital organs.

In this situation, an implantable cardioverter defibrillator (ICD) can monitor the heart and treat the arrhythmia within a matter of seconds using an electrical shock that restores the heartbeat to a normal rhythm. Unfortunately, the majority of patients who are candidates for ICDs have not yet received appropriate treatment.

Life-saving technology for weak hearts

Lake Health offers procedures for all cardiac devices including pacemakers and defibrillator implantation. Our ICD devices and procedures include:

Transvenous ICD
This battery-powered device is placed under the skin of the collarbone, where it monitors and records your heart rate. Thin wires (called leads) are threaded through your veins and placed in your heart chambers. If an irregular heart rhythm is detected, the device delivers a life-saving shock to restore a normal heartbeat.

S-ICD
This implantable defibrillator sits under the skin of the rib cage, leaving the heart and veins untouched. It uses an electrode that analyzes the heart rhythm. If it senses an irregular heart rhythm, it delivers a life-saving shock to restore a normal rhythm. Because it carries a lower risk of infection, it’s a good choice for hemodialysis patients.

Cardiac resynchronization for congestive heart failure patients
This procedure involves implanting a device under the skin of the collarbone. An additional lead (or wire) can be attached to a pacemaker or ICD to help improve heart function and treat heart failure. This lead is threaded to a vein that wraps around the left side of the heart, where it regulates the left lower chamber of the heart.

LifeVest
This wearable defibrillator vest continuously monitors your heart with non-adhesive electrodes that detect irregular heart rhythms. If an abnormal rhythm is detected, the device alerts you, releases a Blue™ gel, and then delivers an electrical shock to restore a normal heart rhythm. The alert allows you to delay the shock if you are still conscious.
